Thank you for the explanation.
Having tried single point slings for a bit, I'm not personally a fan, although they do have their uses in certain situations with the right gun.
We have a demo 11.5" AR pistol that has a single point on it sometimes.
That's why I like the 221, it can go from two point to single point easily, depending on the situation.
It's what we sell to a lot of our LE Department customers, as they can issue them out, and can be configured as the Officers see fit.
As for the caliber, I think Beat Trash pretty much summed up my thoughts. We sell RA556B to our LE customers. If it can put down people, I figure it should be good for a mountain lion. Maybe DocGKR can chime in?
